December weather forecast
Fannie Bay, Australia

December, the first month of the summer in Fannie Bay, is still a hot month, with an average temperature varying between 32.5°C (90.5°F) and 27.8°C (82°F).

Temperature

The dawn of December sees an average high-temperature of a still tropical 32.5°C (90.5°F), subtly contrasting with November's 33.3°C (91.9°F). Fannie Bay encounters a negligible difference from daytime peaks throughout the December nights, with a low-temperature average of 27.8°C (82°F).

Heat index

The heat index value for December is computed to be an extremely hot 43°C (109.4°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

The average relative humidity in December in Fannie Bay is 72%.

Rainfall

In December, the rain falls for 27.7 days. Throughout December, 204mm (8.03") of precipitation is accumulated. In Fannie Bay, Australia, during the entire year, the rain falls for 191.8 days and collects up to 1282mm (50.47") of precipitation.

Sea temperature

December is the month with the warmest seawater, with an average sea temperature of 31.5°C (88.7°F).
Note: Seeking solace in water that's above 30°C (86°F) in temperature might not provide the anticipated relief from the heat.

Daylight

With an average of 12h and 48min of daylight, December has the longest days of the year.
On the first day of December, sunrise is at 6:11 am and sunset at 6:59 pm. On the last day of the month, sunrise is at 6:24 am and sunset at 7:15 pm ACST.

Sunshine

In December, the average sunshine is 8.4h.

UV index

January through October and December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for ordinary individuals.
Note: In December, the maximum UV index of 7 suggests this advice:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
